Can't create Anaconda environment with python=3.4 - anaconda

Question

I'm trying to set up a Anaconda environment with Python=3.4.
(base) C:\WINDOWS\system32>conda create -n py34 version=3.4
I already include the conda-forge channel, but still get this error:
Collecting package metadata (current_repodata.json): done
Solving environment: failed with current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
Solving environment: failed
PackagesNotFoundError: The following packages are not available from current channels:
- version=3.4
Current channels:
- https://repo.anaconda.com/pkgs/main/win-64
- https://repo.anaconda.com/pkgs/main/noarch
- https://repo.anaconda.com/pkgs/r/win-64
- https://repo.anaconda.com/pkgs/r/noarch
- https://repo.anaconda.com/pkgs/msys2/win-64
- https://repo.anaconda.com/pkgs/msys2/noarch
- https://conda.anaconda.org/conda-forge/win-64
- https://conda.anaconda.org/conda-forge/noarch
To search for alternate channels that may provide the conda package you're
looking for, navigate to
https://anaconda.org
and use the search bar at the top of the page.
When i try it with:
(base) C:\WINDOWS\system32>conda create -n py34 python=3.4 -c conda-forge
I get:
Collecting package metadata (current_repodata.json): done
Solving environment: failed with current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
Solving environment: failed
UnsatisfiableError: The following specifications were found to be incompatible with each other:
Package vc conflicts for:
python=3.4 -> vc=10
Package pip conflicts for:
python=3.4 -> pip
Package vs2010_runtime conflicts for:
python=3.4 -> vs2010_runtime
I'm pretty new to Anaconda and Python and dont know what to search for anymore.
This post: Why conda cannot create environment with python=3.4 installed in it didnt help either.

Answer 1

Firstly you can provide more details by increasing the verbosity of the create command, which will provide useful debug messages. Each -v increases the verbosity from INFO to DEBUG to TRACE. I normally always use DEBUG because I hate seeing it just sit there when solving an environment.
conda create -v -v -v -n py34 python=3.4
I don't believe you needed to add conda-forge, the problem with your first command was that you didn't specify python=3.4, you did version=3.4. Try it without conda-forge and including python=3.4 instead.
It also looks like your conda is broken, it's failing to resolve the environments which is likely not helping the situation. Try to fix that with
conda update --all
If you are still stuck with the same problem then review the conflicts with the following commands
conda info vc
conda info pip
conda info vs2010_runtime
I believe there is a chance that some of the packages in your base are incompatible with 3.4. In this case you could try to install without any default packages
conda create --no-default-packages -n py34 python=3.4
If you are still running into issues, there is a chance there is something janky with your config files, so I would try doing a complete uninstall of anaconda on windows. And then attempt this again.

Ok, 3 days later i found out that the latest Version of Anaconda is kinda broken. I downgraded to version 4.6.14 and now everythings seems to work.
conda config --set allow_conda_downgrades true
conda install conda=4.6.14
